f 11 claims. (cl. zas-z8) 'I'his invention relates to dispensers forcarbonated drinks and lhas for an object to provide l a new and improveddevice ofthisdescription.

` The invention has as a further object to provide a'- dispenser forcarbonated drinks which v shall be-,small in size, and which shall have-all i vthe features ofl a large dispenser, such as a mixf ingdevice'for mixing the syrup and the carvide a dispenser of the kinddescribed whiclr can be placed on the soda fountain counter.

'I'he invention has other objectswhich will'be more particularly pointedout in the accompanying description. i n l Referring now to thedrawings,Fig. 1 is a vertical sectional view through one form of the dispenserembodying the invention; and

Fig. 2 is a plan view of the dispenser illustrated in Fig. 2:

Fig.- 3 is'a sectional view through the mixing chamber. p

Like numerals refer to Vlike the several n gures. l

Referring now to the drawings, I have illustrated a dispenser consistingof an outer casing I and an inner kcasing" 2 separated by a space, whichspace is iilled with' some heat insulating material 3. Within the'innercasing 2 is an ice parts throughout chamber I and a syrup container 5located in the ice chamber, `,and preferably arranged so that'it 'mayhave ice 'on all sidesthereof. Located in the ice chamberis a coolingcoil 6, through which the carbonated water passes. There is an inlet 1for thel carbonated water, whichinlet is `connectedby the connectingmember 8 with the end to be discharged through the dispenser nozzle .|2.

This mixing ,chamber may, be `of any :suitable form, such as that, forexample, described` in my 'A prior lapplication 'Serial No. 737,320.

'Ihe connecting member I3 is connectedo by a;

connecting piece Il with a han'dle I5 on the outside of the device, thehandle 1s vbeing pivote@ at i6 to a support l1,

attached to' the outside calsing. There isa stop, I8, connected with-thecon-A necting member I 4,; which 'stops the ,movement of the handle. lTheconnecting member I3 of the Vdraftfaairm ispivotally connected withthe connecting "pie'ce Il by the pivotji!l and this conpiece Il isconnected by the pivot 2l with the handle I5.' Attached to the innercasing 2 is a strengthening member 2 I which has a portion extendingalong the bottom of the casing y2 and has an vannular hollow part 22,through which the beverage is discharged and which receives thedispenser nozzle I2.

The mixing chamber II is attached to the inside of the inner casing 2,'lwhich forms the ice chamber. the attachment being made by means l`of afastening device 23, whichhas a screwthreaded end 24 which enters thethreaded opening inthe strengthening member 2|. ,This fastening member23 4preferably has@ knurled head 25 so that it may easily and quickly beremoved to disassemble the parts. 'I'he syrup container 5 is mounted inthe ice chamber and is supported at the rear by the support 26.- VThesyrup container 5 is' provided with a discharge member 21, whichconnects with,A4 the mixing chamber Il so as to. discharge syrup in themixing chamber. 'I'his discharge member 21 is pivotally connected withthe dispenser. by a swivel joint 28. Connected with the syrup containeron the side of the mixing chamberl opposite to that in which thedischarge member 2] is locatedl is Aa projecting member 29, having athreaded opening, through which passes a clamping screw having a knurledhead 3|.- This' clamping screw engages the mixing chamber and whentightened up, it and the projecting part 29 and the discharge member 21connect the front end of the syrup container with the mixing chamber soas to hold the parts in proper relation.

It will be rnoted that the-.mixing chamber is mountedclose to the-bottomso as to' make Ait possible to have a syrup container, to get thedesired amount `of syrup necessary for/practical dispens- When it isdesired ato empty vthe syrup container the stop I8 is moved up out ofthe path of the handle I5. The handle can then be moved backward to agreater extent than under normal l operation and this opens up to agreater extent the discharge of the syrup container and permits thesyrup to quickly run out. This is particularly Iuseful for washing andcleaning the syrup container and the mixing chamber and associated Thereis a drain pipe 32 -fcr discharging the water produced by the melting ofthe -ioe in the ice receptacle. There is an air vnt'33 leading from thecompartmentin the chamber' wherev the syrup is depositedfrom the syrupreg ce'ptaclel when 'the handle i5iis operated, whicl'i permits the airtoescapeso as to' let the syrup ow in. 'I'he 'air vent has its end bentdownward- 1y to about the level of the top ofthe drain pipe 32, whichprojects upwardly into the ice chamber. If the drain pipe becomesstopped, the water accumulates in the ice chamber until it rises abovethe mouth of the air vent. 'I'his prevents. the escape of the air andstops the flow of the syrup into the mixing chamber, and makes itimpossible to draw a mixed drink from the dispenser when the handle I ismoved. The operator is thus apprised oi the fact that the drain pipe isstopped and can-take the necessary steps to clean it out. 'I'heconnecting piece I4 passesthrough the inside wall and the outside wallor shell and hence -there must be an opening on both of these walls forthis purpose. Means are provided which will prevent water from passingout through these openings in' the event the drain should becomestopped. To prevent this waste water from -running into the heatinsulating material `and also from following the connecting piece I4 tothel outside of the device, I provide a housing 36, which seals theopening in the wall 2 and which is arranged to catch any overilow water.This housing is provided with a drain 31 to .permit the water to bedischarged into the "ice chamber. There is also a shield 38 for themembers I3 and I4, arranged to shield them from the ice `in` the icechamber'.

Referring now to the mixing chamber, the connecting member I3 actuatedby the handle I5 is connected with the shaft 4a so4 as to rotate it whenthe handle is moved. Connected with this shaft is a cam 32a which, whenthe handle I5 is rocked, engages the member 32h on the top of the y pins32e. These pins engagethe valve 32d, see

Fig. `3. The cam 32a. presses them downwardly so as to open the valve32d to let the syrup into the nozzle ,through the openings 23a. When thevalve 32d isLopened, the syrup from the syrup receptacle passes into thechamber vBla-through openings 23a which communicate with chamber 22a,and into the space 30a and then down into 5ggk the upper part of themixing chamber II is a4 connection 20a. which communicates with theoutthe lower part of the nozzle. The cylinder 29a is closed at the topand the charged water passes down into it through the pipe 33a, passingout through the openings 34a. Atspring 35a sur- -rounds the lower end ofthe pipe 33a, its lower end being supported Ourthe-member 36a. Thisspring returns the valve 32d to its closed position when the pins 32eare released by the cam 32a by turning the handle back. 'I'he member 31apasses through this member 36a., as shown in Fig. 3. At

side atmosphere, discharging atmospheric air into the chamber 22a toinsure the proper discharge of the syrup therein. .i c l When the partI5l is moved to open the valve 32d, the cylindrical part 5a is moved soas to move the openings 21111 and 2Ia. out of register and close off theadmission of the'syrup into the chamber 22a. In this position, the airpassage 20a in the part 5a communicates with the member 33 and hencewith the outside atmosphere. The rotation of the valve operating member4a to open the valve 32d also opens the valve 44 which admits the sodawater from the pipe 44a into the/:passageway 33a and out through theopenings 34u. so as to mingle with the syrup. The Soda water valve 44 isopened by a cam 45 which engages a pivoted arm.46, one end of whichengages the stem 41 of the valve 44 so as to open said valve. A spring48 returns the valve, when the A'up and carbonated water, a'han handleI5 is moved, back to its` initial position. The spring and valve aremounted in a cylindrical holder 48a which has one end projecting into asleeve 48h provided on its exterior with a series of grooves 48eextending there around. A screw 48d passes through the wall of themember I I and has its end projecting intov one of these grooves so asto hold vthe parts in' position. When the -syrup, by opening the valve32d, passes from the openings 23a into the chamber 3Ia and passes downinto the space 30a, its movement is slowed down and thespacevbetween'thef edge of the part 21a and the .part 24a iscomparatively small so that the same amount of syrup will be,

discharged each tinie. There is also an air passage 40 up through thenozzle to the .top ofthe mit the soda water, the ports .20b and 2Ia aremoved out of registerso that no more syrup can enter the measuringchamber 22a. and hence this 'measuring chamber measures the quantity ofsyrup to be mixed with the soda water for each glass of the liquid.
